WAVEFORM DISPLAY APPARATUS AND WAVEFORM DISPLAY METHOD

PROBLEM TO BE SOLVED: To overcome the problem wherein analysis of tendency in the measured physical quantity and detail reading of the current physical quantity cannot be implemented simultaneously, since adjacent waveforms displayed on a display are mixed. SOLUTION: A waveform display apparatus 10 is provided with a measurement section 4 for measuring the physical quantity of a to be measured object; a storage section for storing time-series data as the physical quantity of the to-be-measured object, measured by the measurement section 4 at each predetermined measurement time; a calculation/processing section for reading the time-series data stored in the storage section, and calculating the ratio at each predetermined measurement time with respect to all measurement times of the time-series data; and a display section 2 for displaying a graph of the physical quantity of the to be measured object measured at each predetermined measurement time, by changing the display width at each predetermined measurement time, based on the ratio at each predetermined measurement time calculated by the calculation/processing section. The apparatus carries out a compressed displaying. COPYRIGHT: (C)2008,JPO&INPIT
